There’s a good round of discussion about the appropriate way to implement a mute switch. Gruber favors the current design. Andy doesn’t.

I agree with Gruber on this one. According to Andy’s design, I would have to go in and manually disable all audible alerts in the settings every time I wanted to use an alarm. Otherwise, the damn phone would be dinging every few minutes from incoming email. Yes, I have audible email alerts. It’s handy since I’m responsible for some important systems staying online and there’s no way in hell I want a pager.
